Custom PTFE Bearings & Slide Plates | Low-Friction Fluoropolymer Bushings

Engineered for high-wear, non-lubricating, and corrosive environments, our custom PTFE bearings and slide components provide an ultra-low friction solution for industrial machinery. Machined from premium virgin or filled PTFE compounds (including carbon, glass fiber, bronze, or molybdenum disulfide), these components eliminate stick-slip motion, prevent metal-to-metal galling, and eliminate the need for external grease or oil lubrication.

Our product lineup includes cylindrical sleeve bushings, flanged sleeve bearings, thrust washers, guide rings, and heavy-duty linear slide plates tailored for precise mechanical motion control.

Key Performance Benefits

• Self-Lubricating Operation: Extremely low coefficient of friction enables smooth, dry-sliding performance without oil or grease contamination risks.

• Exceptional Chemical Resistance: Impervious to virtually all industrial acids, alkalis, solvents, and aggressive process fluids.

• Broad Operating Thermal Window: Maintains dimensional integrity and mechanical stability across temperatures from -200°C (-328°F) to +260°C (+500°F).

• Zero Stick-Slip & Low Wear: Delivers consistent breakaway torque and smooth linear motion in slow-speed, high-load sliding applications.

• Non-Conductive & Dielectric: Excellent electrical insulation properties safeguard sensitive automated equipment and electronic assemblies.
